What Is an Embedded System and What Can Embedded System Developer Do?
According to the recently updated Cisco Visual Networking Index, there are expected to be more than 28 billion networked devices by 2022. These devices surround us on a daily basis and no wonder that embedded systems are rapidly growing driven by the power of the IoT. What is an embedded system and how it benefits the today world?
An embedded system is an integrated system built with a combination of computer software and software (called Firmware) designed to perform one function greatly over and over again. In some cases, embedded systems can be projected even for managing the whole operating system.
Though embedded systems are computing ones, usually, they are designed to perform one and the only task having no UI (user interface). But there are a lot of embedded systems that have complex GUIs (graphical user interfaces) with buttons, touchscreen sensor, LEDs as, for example, in mobile devices. A remote UI can be applied as well.
As you can see, some embedded systems can be very simple, other ones support human decision-making or command set but the main thing is, embedded systems are designed to perform one function. They are not expected to perform any additional functions besides the projected one, so these systems proved to be more reliable and durable compared to variable ones. Besides the reliability, they are not interchangeable which proves the importance of the embedded systems. Usually, complementary systems are modular or alterable but when it comes to the embedded systems, they are integrated into the core system.
Here are more pros of using embedded systems:
- they are reactive because of sensors and actuators triggered
- little power consumption because of the single function performed
- fits in a small space
- rarely need any hardware or software change
- the best solution for devices that don’t require user-end operations
- the best solution for devices that don’t need to be frequently updated
Basically, most everyday devices have an embedded system integrated into it, including a mobile phone, a car, a watch, a microwave, a washing machine, etc. Such IT devices as routers and switches are also built with the help of embedded systems. But there’s a bigger picture here: almost all industrial, medical, automotive, agricultural, aerospace, household devices have embedded systems in them. If we talk about IoT applicability, smart homes, drones, 3D printers, wearables, and others are growing in embedded system usage.
What specialist can develop embedded systems? It is the embedded software developer, also referred to as an embedded hardware developer is a computer engineer with expertise in the major computer languages like Java, C++, Python, C, and other high-level languages and electronic hardware, microcontrollers, and PCB boards. The knowledge of Linux operating systems is also very critical for an embedded system design engineer or embedded Linux programming. The embedded Java developers and embedded Linux developers are also hired by embedded systems companies nowadays.
People say that embedded system developers are overrated. But if take a look at the tremendous number of skills and knowledge needed to be the embedded system expert, it makes sense why such professionals set corresponding prices for complex embedded system development. Here is just an average embedded system developer skill set for you to consider:
- 2+ years of C/C++ and Assembly development, ADA, Python, VHDL will be a plus
- long experience with microcontrollers and microprocessor systems (Arduino, Raspberry Pi, etc)
- knowledge of different types of memory and memory-based software
- previous experience with electrical circuit designs, debugging and testing of integrated circuits and components
- understanding of CAD software basics (AutoCAD, SolidWorks, etc)
- experience with digital measurement instruments
- strong knowledge of IoT frameworks (Google Cloud Platform, IBM Watson, etc)
- data analysis
- technical writing
Impressive, right? That’s a bare minimum of what embedded system programmers deal with every day. Ready to hire one for your project?
